Evenity is a relatively new drug, and not all of its side effects seem to be known. More than few doctors seem dismissive when women complain about symptoms that did not appear during the testing phase of this drug or symptoms that appeared in only a small segment of the testing population. Still, if you can get through taking the injections for a year or at least six months, it is worth the benefit of having stronger bones. Keep going as long as you can, but do not be afraid to quit if your symptoms worsen or become unbearable.
